are there any open hardware projects to create such point clouds?

I would really like to see that as well. The rendering is interesting, but only as a passing curiosity if we can't author data.

You might be interested in OpenDroneMap [1] and Mapillary's OpenSfM [2],[3]

Yes. Point clouds are created mainly using two technologies: 1) structure from motion (SfM) and 2) light detection and ranging.

SfM is a photogrammetry / computer vision method that can produce 3D point clouds from photographs of objects taken at multiple angles. It is a passive method that uses only the light reflected from the object.

LiDAR uses laser ranging to actively measure the 3D geometry of a scene.
